Hello.
I'm trying to get 3-phase pwm signals for aci motor using LAUNCHXL-F28069M board. I'm using general code proj_lab01b. I don't have a motor, and any power of feedback schemes. The problem that I can't get pwm looked signals for ACI motor. I can see only pwm modulation frequency ~5KHz on EPWM outputs.
Here is my motor configuration:
#elif (USER_MOTOR == Dayton_2N865T)
#define USER_MOTOR_TYPE MOTOR_Type_Induction
#define USER_MOTOR_NUM_POLE_PAIRS (2)
#define USER_MOTOR_Rr (2.540533)
#define USER_MOTOR_Rs (4.681129)
#define USER_MOTOR_Ls_d (0.02621018)
#define USER_MOTOR_Ls_q USER_MOTOR_Ls_d
#define USER_MOTOR_RATED_FLUX (0.8165*230.0/60.0)
#define USER_MOTOR_MAGNETIZING_CURRENT (1.838921)
#define USER_MOTOR_RES_EST_CURRENT (1.0)
#define USER_MOTOR_IND_EST_CURRENT (NULL)
#define USER_MOTOR_MAX_CURRENT (5.0)
#define USER_MOTOR_FLUX_EST_FREQ_Hz (5.0)
#define USER_MOTOR_FREQ_MIN_HZ (2.0) // Hz
#define USER_MOTOR_FREQ_MAX (60.0) // Hz
#define USER_MOTOR_FREQ_LOW (5.0) // Hz
#define USER_MOTOR_FREQ_HIGH (50.0) // Hz
#define USER_MOTOR_VOLT_MIN (35) // Volt
#define USER_MOTOR_VOLT_MAX (230.0) // Volt
Can you help me? What I'm doing wrong?
